SUBRADIUS Ron FOR AUTOMOBILES.

Specifieation'of Letters Patent. Patented J 311.; 25, 1921.

Application filed August 2, 1919. Serial No. 314,921.

To all whom it may concern:

Be it known that I, ALLEN E. BosLmga citizen of the United States, residing at the city of St. Louis, Stateof Missouri, have invented a certain new and useful Improvement in Subradius Rods for Automobiles, of which the following is a full, clear, and'exaet description, suchas will enable others skilled in the art to which it appertains to make and use the same, ref.- erence being, had to the accompanying drawings, forming part ofthis specification, inwhich- Figure 1 is a top plan view of my improved sub-radius rod.

Fig. 2 is a vertical sectional view taken through the crotch of a main radius rod.

Fig. 8 is a detail view of the casting employed in connection with the sub-radius rod.

Fig. 4 is a plan view of the junction of the members of the sub-radius rod, and

.Fig. 5 is a perspective'viewofa modified form of my'improved radius rod.

This invention relates to a new and use ful improvement in sub-radius rods for au tomobiles, the object being to provide a relatively simple and inexpensive rod and one which is effective in service in that being connected to the lower side of the front axle of a well known type of automobile and extending rearwardly where it is connected to a thrust block, it will transmit strains from the lower side of the axle to the crotch ofthe main radius rod.

In the drawings, 1 indicates the main radius rod which, as usual, is provided with a ball 2 at its rear end which engages a socket in the engine frame. This main radius rod is connected to the top ofv the front axle of the automobile, and in order to reinforce and support the front axle, I provide my improved sub-radius rods 3 which are connected to the lowerside of the front axle. These sub-radius rods, or rod, as it might be called, when formed from a single piece of angle iron, has its forward. end connected to the lower side of the spring perches and is V-shaped in general form, the flange of the angle being presented inwardly, as indicated in the drawings. Inbending the sub-radius rod, the

- surplus metal at the junction of the two legs is crimped and the metal caused to flow slightly, but in order to avoid additional thickness incident to this condition, if

I flatten theflange out to substantially its original thickness, which means a widened and reinforced flange at the junction of the legs of the sub-radius rod, as shown at 3. The downwardly extending portionof the angle iron 3* of the sub-radius rod is thus located on the outer side of the curve at the junction of the legs and forms a solid shoulder which is received in a casting 4, said casting constituting a thrust block, which is; provided with a seat in its lower face to receive the sub-radius rod, and a projection on its upper face, indicated at l, for engagement with the crotch of the main radius rod. 7

There is a flange l provided at the forward upper edge of the casting for cooperating with the clamping plate 5, which clamping plate extends over the main radius rod at substantially the point of the crotch thereof and is perforated to receive a clamping bolt 6 which passes down through the casting and through the widened flange at the junction of the legs of the sub-radius rod. The clamping plate prevents any forward displacement of the parts and the thrust block transmits all strains imposed on the sub-radius rod to the crotch of the main radius rod.

In some instances, it may be found desirable to construct my improved sub-radius rod in two parts and when such construc tion is employed the parts are formed preferably from angle iron and each part disposed with its apex uppermost and consequently having its diverging flanges downwardly and outwardly presented (see Fig. 5).

The rear ends, of these members, designated-by the numeral 7, are flattened so as to provide "horizontally disposed plates 8 which, when properly assembled, are disposed with one directly on top of the other and these plates are perforated, as designated by 9, in order to receive the clamping 'bolt 6. If desired, the sub-radius rods when separately formed, as just described, may be constructed of metal tubing, thereby combining strength and rigidity with minimum weight.

It will be readily understood that minor changes in the size, form and construction of the various parts of my imprpved subradius rods for automobiles may be made and substituted for those herein shown and described, without departing from the spirit of my invention,the scope of whichis set forth in the appended claims.

I claim:

g 1. In combination with a main radius rod, a sub-radius rod angular in cross-section and arranged under the main radius rod, said sub-radius rod having its horizontal flanges presented inwardly at the point of junction of its converging legs, a casting having a flange at its lower edge forming a seat for the junction portion of the, subradius rod, said casting arranged in and engagingthe crotch of the main radius rods, there being a lip or flange at the forward upper edgeof the casting, a clamping plate extending over the main radius rods at substantially the point of the crotch thereof and engaging said upwardly extending flange at the forward edge of the casting, and a bolt passing through said clamping plate casting and junction flange of the sub radius rods.

provided with a seat in itslower face, a subradius rod angular in cross section and bent at its converging ends so as to engage the seat in the lower face of the casting, the horizontal flange of the sub-radius rods at its point of junction being wider than the horizontal flanges extending along the leg portions ofthe sub-radius rods, a clamping plate arranged above the main radius rods, and a bolt passing through said clamping I plate casting and widened horizontal flange of the sub-radius. rod at the junction of the subradius rods forsecuring the parts 'together. 7 j

In testimony whereof I hereunto affix my signature this th day of July, 1919. V
